Good King Wonderful can be very overpowered, as its floop can heal ANY creature to all health, which means it can heal itself and other creatures if they are low on health. Thus making him nearly invincible.

Use Wizard Rawk on it when its low on health, then flop it, and heal itself to buff it to high attack and defense. Also, increase its defense to make it a better attack resistor and increase the effectiveness of the strategy above.

Try to fight him with creatures with more or with 40 attack, which kills him instantly. A good creature to battle Good King wonderful with is the Corn Ronin, as it can gain attack as it's floop. Use Skull Juice to switch its attack and defense then you can beat it with Cerebral Bloodstorm, damaging floops, or just hit it enough.

Another strategy is to lower its attack to 0 and use a card like Cool Dog or Mouthball to keep it from using its floop until you can kill it.

Good King Wonderful is a 5 Star, Algebraic Rare Nice Lands creature in Card Wars. It can be obtained through the Algebraic Chest, or as loot in battle. It is the 2nd-10th prize card in the 5th Deck Wars Tournament.
